*WILLIAM Barren iviaitiiiv, or;ia'nnorig'wrscoiisin.

To all fwkomz'tvmayconcern.;1 y Y WILLIAM BAIRDv MAR- Be it known that l, TiN, a citizen of the United States, residing at Beloit, ,inthe countyof Rock, State of l/Visconsin, have 'invented a new and useful. OvenLShelf; Yand'fdo hereby declare the following to be a full, clear, and exact dei' scription of the invention, such as lwillenable others skilled in the art towhichit appertains to make land use thesame. f

The invention relates toeven shelves and has for its object. to provide a shelfwherein, the necessity ofl turning the article be, ing baked around in the oven yby hand,A

which operation oftenresults in the burning of the hands, is eliminated. Whenbaking cakes it is particularly necessary to turn the cake in the oven, otherwisethe same will not be evenly baked nor will it be of a uniform brown.

A further object of the invention is to provide one or more revolving disks, having gear connections with gears revolved by a shaft, said shaft being "provided with a detachable handle located outside the door of the oven whereby the shaft may be revolved, thereby revolving the baking disks.

A further object is to so construct the mechanism for turning the disks that disks of different sizes may be used, or if desired one disk may be used. Also to so construct the mechanism for turning the disks, ,thatV when it is desired to eliminate the use of disks', it will onlybe necessary to turn the shelf over thereby presenting a sur-v face which may be used for vvessels for cooking. Y .y

vWith the above and other objects in view, the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings and claimed, it being understood that changes in the precise embodiment 'of the invention may be made within the scope ofwhatis claimed without departing from the spirit of the invention.

In the drawings Figure 1 isa front elevation of a stove, showing the glass oven door. Y

door is provided with Yagglassor-,transparent` 'f panel 5, through which the articles that' arey being cooked or baked within the oven',may

be seen at alltimes.` e

y Theside walls G ofthe oven'areprovided with the usual shelf guides 7, Ywhich are so: arranged as to receive'and support the removable shelf 8, said `shelf being provided with openings 9, through which the hot air f passed/thereby allowing a uniform tempera# ture as faraspossible throughout the oven chamber. It isgto be understood that one i' poses of illustration only one4 shelf is shownl or more shelves may beused, but for 'purand described. l

Secured' to the shelfbymeans of rivets 10 is a series of alined castings 11, said castings beingv located substantially centrally of the shelf.Vv A bearing 12 is secured to the frontend of the shelf by means of rivets 13,

'a rotatable shafty14being mounted in the bearings 12 and bearings 15 ofthe castings l1, there being collars' l'pinned to the shaft whereby longitudinal movement ofthe shaftl 'is prevented. One end of the shaft terminates in registration with an aperture 17 inthe glass door, said shaft being adaptedAV f to be rotated by means of an operatingl handle 18 located outside of the door. Adjustably secured to the shaftv 14, by means of setscrews 19 are gears 20, v21 and 22 which revolve with the shaft 14.v

ing 23, in which the pins 24 of the plates 25 revolve, said bearings 23 being infverticalvalinement with the shaft 14. The plates are' on their lower surfaces .provided .with ,cir-v cumferentially arranged gear teeth 26, which mesh with the gears20 and22. However when it is desired touse a larger plate 25a, the small plates are removed and thev larger plate is kplaced on the shelf.

oven is not opened but the handle 18 isV passed through the aperture 17 in the glass of the oven door and engages the end of the shaft, then 'the cook grasps the handle 18 and imparts a revoluble movement to the same, this Vaction revolving the shaft la and gears thereon.y The gears'being in mesh with the gear teethion the plates, conse, quently Vrevolve the same, which in turn revolve the cake. lVhen the cake has been turned far enough the handle i8 may be removed or left in position for furtherV operation. The turning operation is repeated until the cake is uniformly baked and browned. From the above it will be seen that the opening of the oven door is eliminated and also the touching of the baking pan is eliminated, which often burns the hands. v

It will also be seen-that by removing the plates and then turning the shelf over, that sok the necessity Aof ,providing two Vtypes of r shelves is eliminated.

The invention having been set forth, what is claimed as new and useful is An oven shelf comprising a body member vadapted to be supported in an oven, said shelf being provided with a pair of spaced bearings,'a shaft rotatably mounted in said bearings adjacent the upper face of the shelf, gears adjustably secured to the shaft,

said bearings being provided with sockets by the shaft maybe rotated forl simultane-4 ously rotating the article supporting plates.

In testimoi'iywheieof have signed my name to'this specification inthe presence of two subscribing witnesses.
